Some Aerological Principles Applying to Airship Design and Operation

Abstract

Abstract In this paper the author discusses some of the problems of wind structure and of vertical air currents. Data are presented on local wind fluctuations of great frequency, on less-frequent, wide-spread wind shifts, and on local vertical air movements. The discussion is not primarily of strong winds and gales as a navigational problem affecting cruising radius, but of those properties of wind structure which may be obstacles to air navigation because of the excessive forces which they may exert on airship structures.
